Turks and Caicos Islands: 5 Day Forecast

Ahoy from Mudjin Harbour in Middle Caicos, Boaby Rock Point in Grand Turk, and Grace Bay in Providenciales. Today at Mudjin Harbour the sun rises at 6:27 AM and sets at 7:17 PM, with the moon 41% lit. With mostly clear skies this evening, it may be a fine night to stargaze; look west after sunset for bright Venus low on the horizon.

Tuesday, August 18, 2026: Fair sailing weather across the islands, matey. Mudjin Harbour starts warm at 80 to 82 F overnight and early morning, feeling like 84 to 88 with humidity around 75% to 77%, east winds 6 to 7 MPH, and 3 foot seas easing to 2 feet by late morning. Cloud cover builds fast after sunrise there, from near clear to around 80% by midmorning, then thins through afternoon while temperatures climb to 86 F, feeling like 97 by midafternoon, with humidity near 73% and just a trace of light sunshowers too small to bother most deckhands. By dinner time it stays pleasant with 83 to 84 F, light northeast winds around 7 MPH, low cloud cover, and 2 foot waves. Grace Bay runs very similar but a touch calmer, holding 2 foot seas all day, 82 to 83 F, and east to northeast winds 6 to 10 MPH, excellent for beachgoing and small boat runs. Boaby Rock Point is the outlier, staying much cloudier through the morning with cloud cover often above 90%, but still warm near 82 to 83 F, feeling like 87 to 91, east winds 8 to 10 MPH, 3 foot seas, and only passing light sprinkles.

Wednesday, August 19, 2026: Another mostly friendly day on the water, though skies shift more through the hours. Mudjin Harbour begins near 81 to 82 F with 2 foot seas, east winds 7 MPH, and clouds thickening before dawn from near clear to overcast, then breaking apart through the morning. Afternoon turns hotter there, up to 86 F and feeling like 96, with humidity easing from the mid 70s into the low 70s, southeast to east winds 8 to 10 MPH, and seas building from 2 feet to 3 feet late day. Grace Bay follows the same pattern with 2 foot seas throughout, 81 to 83 F, east winds 9 to 14 MPH, and a few light early sunshowers that fade away, though cloud cover swells again in the afternoon and evening, so outdoor dinner plans should still be fine but a bit more muggy by sunset. Boaby Rock Point starts with a few light showers overnight, then steadily improves to sunnier midday conditions near 83 F, feeling like 89 to 91, before evening clouds return with east winds freshening from 10 to 15 MPH and steady 3 foot seas. The biggest difference again is Grand Turk, where winds rise more by evening than the other spots, making it a touch breezier for supper by the shore.
